Record companies are on the road to recovery from decreasing CD sales with the help of a new di music format provided by London digital music company Digimpro.

Roots Manuva new track Too Cold ? released today ? comes with the new di music player that gives fans the ability to edit and personalise tracks using alternative, original material that is also included with the single, and resave them as MP3 files. The scope of the alternative materials is unlimited, with Roots Manuva providing a number of alternative vocals, guitar, drums and base tracks.

Far beyond traditional remix software, di also allows for real time and randomly generated remixes using these alternative tracks. Available for both download and CD sales, the di player can produce almost infinite variations and works on all PCs and can be transferred to digital music players.

The new single contains enough alternative tracks to be able to create an almost indefinite number of versions. With that many combinations no two are ever going to be the same, so each version is truly personal.

Will Ashon, owner of Big Dada, said: ?I think that with the general decline of singles sales and in particular, the failure of CD singles to really capture the imagination of music buyers, the Digimpro player and file format genuinely offers something more to the fan base of an artist like Roots Manuva.?

?It's fun to play with, surprisingly powerful, and offers the listener a way 'inside' the music. Even studio professionals I've shown it to, surrounded by all the software under the sun, have been drawn in by the simplicity of the interface and the excellence of its application... It's fun!? Ashon said.

Rupert Evans, Managing Director of Digimpro, the developer and owner of di, said the idea came from the need for a new kind of format that was for all artists and music fans.

?The computer age has given us the ability to listen to music in exciting and sophisticated new ways. So far this potential has been largely untapped, but the di format brings these new possibilities to life in a really simple way for artists and fans alike,? Evans said.

?di offers artists new creative possibilities and enables the music industry to use a new format to drive sales. We are in discussions with a number of other labels and we?re confident di will become a standard inclusion on major single releases and add significant value to digital downloads,? he said.
